Physical attraction is the difference between your best friend in the world and a boyfriend/ girlfriend. Looks are important to me, although I actually don't like standard supposedly handsome men, I always go for someone unusual looking, quite a few times people have said to them they have done well to get with me/ punching above their weight which is kind of rude (sorry if that sounds big headed, I don't see it that way).

Part of it is probably how quickly people expect to get intimate, often before they have had a chance to get to know the person or fall in love.
